Siltronic AG

Perfect Silicon Solutions

Operating on a global scale, we are a leading manufacturer supplying the global semiconductor industry with top-class silicon wafers. Employing a workforce of around 4,100, Siltronic has a global network of state-of-the-art production facilities in Europe, Asia and the USA, including top-notch production facilities for 200 mm and 300 mm wafers currently located in Singapore.

Siltronic's extensive product portfolio ranges from non-polished wafers to epitaxial wafers with diameters of up to 300 mm. The wafers are made from monocrystalline silicon ingots which are produced either using the Czochralski technique (CZ) or the float zone technique (FZ). As the crystal properties are crucial for the functionality of semiconductor components, we provide multiple processes to ensure the optimal material properties for each customer's specific application. These processes involve the targeted application of doping substances and precise control of the crystal's cooling profile. The surface finish of the wafers is also tailored to the specific application, ranging from simply sliced to polished on both sides and epitaxial surfaces.
